Abstract

Circuito de criptografía (21) que incluye una clave funcional kc para ejecutar un algoritmo de criptografía, incluyendo dicho circuito una segunda clave ki, caracterizado porque dicha segunda clave es apropiada en cada instancia de dicho circuito, permitiendo proteger a éste contra los ataques que aprovechan los canales auxiliares de dicho circuito; siendo enmascarada la clave funcional kc mediante la segunda clave ki combinando las dos claves mediante la operación XOR, siendo cifrada una variable de entrada x mediante la clave enmascarada kc ⊕ ki; siendo creada la segunda clave ki mediante una función físicamente inclonable o PUF.
